Search for invisible Higgs boson production with the CMS detector at the LHC

Results are presented for the search for invisible Higgs boson production using the full LHC dataset corresponding to integrated luminosity of 5.1 fb^-1 and 19.6 fb^-1 of proton-proton collision data at sqrt(s)= 7 TeV and 8 TeV (respectively) collected by the CMS detector. The invisible Higgs is searched for in final states of missing transverse energy, with two leptons from a recoiling Z boson. No significant excess is found beyond standard model predictions, and limits are obtained on the branching fraction of the Higgs boson to invisible particles.Comment: 9 pages, 8 figures, DPF 2013, The Meeting of the American Physical Society, Division of Particles and Fields, Santa Cruz, California, August 13-17, 201

AN ESTIMATION OF DISPOSABLE PERSONAL INCOME OF THE SPANISH MUNICIPALITIES IN 1997

Since 1992, Lawrence R. Klein Institute –Autónoma University of Madrid- estimates the disposable income of the Spanish municipalities, recently published in the ‘Anuario Comercial de España’ –Spanish Trade Yearbook- as scaled levels. Municipal personal income has been considered as one of the most important economic indicators, very used in a wide range of studies concerned with regional convergence, welfare analysis, marketing targets, etc. This kind of estimation can be carried out by both direct and indirect methodology. The first proceeding requires a huge information database generally difficult to obtain and not always precise, which main defect is that it cannot reflect the underground economy of Spanish municipalities. That is why direct methodology always has needed the help of indirect proceedings. These last ones find out the statistical relation of the personal disposable income and a group of socio-economic indicators for all the geographic units considered, municipalities, provinces, regions, countries, etc. In this paper, the authors present some of the indirect methods used to estimate the disposable income of Spanish municipalities. Especially the Klein estimation combines some multivariate analysis –panel data, factor and cross-section regression analysis- with a big database of almost 200 socio-economic indicators. The final estimation of the 8.099 municipalities disposable income allows us to acquire a better knowing of Spanish micro-territorial development.

Time-trend in spatial dependence: Specification strategy in the first-order spatial autoregressive model

The purpose of this article is to analyze if spatial dependence is a synchronic effect in the first-order spatial autoregressive model, SAR(1). Spatial dependence can be not only contemporary but also time-lagged in many socio-economic phenomena. In this paper, we use three Moran-based space-time autocorrelation statistics to evaluate the simultaneity of this spatial effect. A simulation study shed some light upon these issues, demonstrating the capacity of these tests to identify the structure (only instant, only time-lagged or both instant and time-lagged) of spatial dependence in most cases.Space-time dependence; Spatial autoregressive models; Moran’s I

Urban growth and territorial dynamics in Spain (1985-2001): A spatial econometrics analysis

The study of the territorial/regional development in Spain has nowadays a relatively long tradition, but from the point of view of cities development the number of studies and documents decreases drastically. This paper tries to improve the knowledge of the Spanish urban system. The aim of this paper is twofold: firstly, to determine the factors that explain the urban growth of Spanish cities; secondly, to observe the cities situation in terms of ¡§winners¡¨ and ¡§losers¡¨ after the long period of integration of Spain in the EU. A spatial conditional ƒÒ- convergence equation is specified and the Durbin-Wu-Haussman exogeneity test is used to check on the existence of simultaneity between urban growth and the control variables. The classic problems of spread and backwash are studied by including a spatial autoregressive term and spatial regimes ¡Vconvergence clubs- in the growth model.Urban growth, Spanish cities, conditional ƒÒ-convergence, endogeneity, Durbin-Wu-Haussman, spatial autocorrelation, spatial heterogeneity, convergence clubs

Building an Environmental Quality Index for a big city: a spatial interpolation approach with DP2

The elaboration of Environmental Quality Indexes (EQI) for big cities is one of the main topics in regional and environmental economics. One of the usual methodological paths consists of generating a single measure as a linear combination of several air contaminants applying Principal Component Analysis (PCA). Then, as a final step, a spatial interpolation is carried out to determine the level of contamination across the city in order to point out the so-called ‘hot points’. In this article, we propose an alternative approach to build an EQI introducing some methodological and practical novelties. From the point of view of the selection of the variables, first we will consider noise -joint to air pollution- as a relevant environmental variable. We also propose to add ‘subjective’ data -available at the census tracts level- to the group of ‘objective’ environmental variables, which are only available at a number of environmental monitoring stations. This combination leads to a mixed environmental index (MEQI), which is more complete and adequate in a socioeconomic context. From the point of view of the computation process, we use kriging to match the monitoring stations registers to the Census data. We follow an inverse process as usual, since it leads to better estimates. In a first step, we krige the environmental variables to the complete surface and finally, we elaborate the environmental index. At last, in order to build the final synthetic index, we do not use Principal Components Analysis -as it is usual in this kind of exercises- but a better one, the Pena Distance method (DP2).Environmental index, Air pollution, Noise, Subjecive expectations, Kriging, Distance indicators

SPACE-TIME LAGS: SPECIFICATION STRATEGY IN SPATIAL REGRESSION MODELS

he purpose of this article is to analyse the dynamic trend of spatial dependence, which is not only contemporary but time-lagged in many socio-economic phenomena. Firstly, we show some of the commonly used exploratory spatial data analysis (ESDA) techniques and we propose other new ones, the exploratory space-time data analysis (ESTDA) that evaluates the instantaneity of spatial dependence. We also propose the space-time correlogram as an instrument for a better specification of spatial lag models, which should include both kind of spatial dependence. Some applications with economic data for Spanish provinces shed some light upon these issues.Spatial dependence, spatial diffusion, ESDA, correlogram, Spanish provinces

The impact of objective and subjective measures of air quality and noise on house prices: a multilevel approach for downtown Madrid

Air quality is one of the major concerns in big cities. It is therefore of interest to evaluate properly air pollution. Specifically, this paper aims at measuring how air quality is incorporated in transaction prices in downtown Madrid. For that purpose, we use multilevel models since our sample is hierarchically organized into 3 levels. Our first-level consists of 5,080 house prices. The second level consists of 759 census tracts while the third level consists of 43 neighbourhoods. We have variables available for each level, individual characteristics for the first level and various socio-economic data for the other levels. The outline of the paper is as follows. First, we combine a set of noise and air pollutants measured at a number of monitoring stations available for each census tract. Second, we apply kriging to match the monitoring station records to the census data. Third, we estimate hedonic models in order to measure the marginal willingness to pay for air quality in downtown Madrid. While the conventional approach to estimate hedonic models is to use ordinary least squares, we exploit the hierarchical nature of our data and estimated multilevel models instead. These allow for a more reliable statistical inference.

Adaptación ilustrada del mito de Perseo como recurso en Educación Infantil

[ES] El presente trabajo pretende acercar los mitos griegos a las aulas de Educación Infantil ya que éstos han sido referentes de multitud de producciones artísticas a lo largo de la historia, llegando a formar parte de nuestro imaginario colectivo. Por su antigüedad, los mitos comparten ciertas características con los cuentos populares, y a pesar de existir adaptaciones destinadas a niños, ni los primeros ni los segundos fomentan su lectura visual. Por ello, este trabajo propone la creación de un álbum puramente ilustrado, basado en una adaptación propia del mito de Perseo, para utilizarlo en un aula de infantil como recurso a través del cual los niños pueden familiarizarse con la mitología y trabajar asimismo tanto la intertextualidad como el lenguaje visual.[EUS] Hurrengo lanak Greziako mitoak Haur Hezkuntzako ikasgeletan ekartzea du helburu, zeren hauek historian zehar hainbat ekoizpen artistikoen erreferenteak izan baitira, gure irudimen kolektiboaren parte bilakatuz. Bere antzinatasunagatik, mitoek herri-ipuinekin zenbait ezaugarri partekatzen dituzte, eta nahiz eta haurrei zuzendutako egokitzapenak existitu, ez lehenak ezta bigarrenak ere ez dute ikus irakurketa sustatzen. Beraz, lan honek guztiz ilustratutako album bat proposatzen du, Pertseoren mitoaren egokitzapen propioan oinarrituta, baliabide gisa Haur Hezkuntzako ikasgela batean erabiltzeko, horren bidez, haurrek mitologiarekin ohitu ahal izateko eta, era berean, testuartekotasuna eta ikus hizkuntza landuz.ÈN] The present work tries to bring the Greek myths to the classrooms of Pre-Primary Education since these have been referents of multitude of artistic productions throughout history, becoming part of our collective imaginary. Because of their antiquity, myths share certain characteristics with folk tales, and although there are adaptations intended for children, neither the first nor the second foster their visual reading. Therefore, this work proposes the creation of a purely illustrated album, based on an own adaptation of the myth of Perseus, to use it in a children's classroom as a resource through which children can become familiar with mythology and also star working both with intertextuality and visual language
